Anschlussklemme zum Aufpressen auf den Innenleiter eines koaxialen Kabels

摘要

A method for crimping a terminal (30) to an end of an inner conductor (20) of a coaxial cable (10) is such that the resulting crimp joint (22) is precisely located a selected distance rearwardly from a mating point of the contact section (32) with a complementary contact section of a mating terminal affixed to an other coaxial cable. The terminal includes an intermediate section (42) of selected length, reduced diameter and location between the body section (34) and the crimp joint, such that, in cooperation with a smaller diameter forward portion (218) of the bore of the connector outer shell (210) coextending therealong, a region of deliberate impedance mismatch results, compensating for other mismatches of the coaxial connection for minimized overall mismatch. A locating fixture (100) affixed to a crimping tool (50) has an aperture (102) includes a stop surface which stops the terminal during insertion through the crimping port (56) of the crimping tool and into the aperture by abutting with a ledge (38) of terminal (30), resulting in a target portion of the crimping barrel (40) being precisely opposed from the tool's reciprocating crimping dies (80,82), to be crimped. Mating connectors (202,302) are affixed to cables (200,300) containing the crimped terminals.
